Sulfonamides of anthranilic esters react regiospecifically with halogenated benzo- and naphthoquinones in the presence of fluoride ions in dimethylformamide. Highly substituted products are thus made available for conversion to a wide variety of highly substituted acridones some of which are difficult to obtain by other means.
